The 15kV 100A polymer cutout fuse replaces the traditional porcelain insulator with silicone rubber composite insulating material, which has the characteristics of light weight (weight reduction by 50%), impact resistance, anti-pollution flashover and long life (≥ 30 years), suitable for:
Harsh environments: high humidity, strong ultraviolet rays, coastal salt spray areas
Frequent operation scenarios: photovoltaic/wind power collector lines, urban ring main unit
High reliability requirements: no need for regular cleaning, maintenance-free design
